The 10 Silicon Valley Companies You Wish You Worked for (or Started)
The history of Silicon Valley is the history of digital technology. To become a part of that history, do you go to work for one of the giants — Apple, Google, Intel, HP, Oracle, Facebook? Or do you catch a wave that hasn't crested yet?
Longtime Silicon Valley venture capitalist turned Stanford faculty member and entrepreneur Andy Rachleff tells his students the best thing they can do is join a mid-size company that has proven its durability but is still growing rapidly. In a recent blog post on the website of his software-driven money management service Wealthfront, he writes:
You get more credit than you deserve for being part of a successful company, and less credit than you deserve for being part of an unsuccessful company. Success will help propel your career. At a fast-growing company, chances are good you’ll have a higher position two years after you join. At a slow-growth company, no matter how good a job you do, you won’t have the same opportunities to advance. When it comes time to leave the successful company, you’ll be able to write your own ticket.
Rachleff's advice is actually geared toward aspiring tech stars who are thinking about going to work at a startup. He says don't. But it sounds equally applicable to going to work for a giant company where you're in danger of becoming just another cog.
In our last post, we highlighted the 10 San Francisco tech companies you wish you worked for based on Rachleff's recommendations. They tended toward the fun and quirky. In Silicon Valley the geeks get serious. Rachleff says these 10 private companies, each with revenue between $20 million and $300 million, are among the best you could join to launch a successful career in tech. (Coming next: 10 tech companies you wish you worked for outside of California.)

Computer Program Can Identify Rough Sketches
First they took over chess. Then Jeopardy. Soon, computers could make the ideal partner in a game of Draw Something (or its forebear, Pictionary).
Application software Graphical user interface
Researchers from Brown University and the Technical University of Berlin have developed a computer program that can recognize sketches as they're drawn in real time. It's the first computer application that enables "semantic understanding" of abstract sketches, the researchers say. The advance could clear the way for vastly improved sketch-based interface and search applications.
The research behind the program was presented last month at SIGGRAPH, the world's premier computer graphics conference. The paper is now available online (http://cybertron.cg.tu-berlin.de/eitz/projects/classifysketch/), together with a video, a library of sample sketches, and other materials.
Computers are already pretty good at matching sketches to objects as long as the sketches are accurate representations. For example, applications have been developed that can match police sketches to actual faces in mug shots. But iconic or abstract sketches -- the kind that most people are able to easily produce -- are another matter entirely.
For example, if you were asked to sketch a rabbit, you might draw a cartoony-looking thing with big ears, buckteeth, and a cotton tail. Another person probably wouldn't have much trouble recognizing your funny bunny as a rabbit -- despite the fact that it doesn't look all that much like a real rabbit.
"It might be that we only recognize it as a rabbit because we all grew up that way," said James Hays, assistant professor of computer science at Brown, who developed the new program with Mathias Eitz and Marc Alexa from the Technical University in Berlin. "Whoever got the ball rolling on caricaturing rabbits like that, that's just how we all draw them now."
Getting a computer to understand what we've come to understand through years of cartoons and coloring books is a monumentally difficult task. The key to making this new program work, Hays says, is a large database of sketches that could be used to teach a computer how humans sketch objects. "This is really the first time anybody has examined a large database of actual sketches," Hays said.
To put the database together, the researchers first came up with a list of everyday objects that people might be inclined to sketch. "We looked at an existing computer vision dataset called LabelMe, which has a lot of annotated photographs," Hays said. "We looked at the label frequency and we got the most popular objects in photographs. Then we added other things of interest that we thought might occur in sketches, like rainbows for example."
They ended up with a set of 250 object categories. Then the researchers used Mechanical Turk, a crowdsourcing marketplace run by Amazon, to hire people to sketch objects from each category -- 20,000 sketches in all. Those data were then fed into existing recognition and machine learning algorithms to teach the program which sketches belong to which categories. From there, the team developed an interface where users input new sketches, and the computer tries to identify them in real time, as quickly as the user draws them.
As it is now, the program successfully identifies sketches with around 56-percent accuracy, as long as the object is included in one of the 250 categories. That's not bad, considering that when the researchers asked actual humans to identify sketches in the database, they managed about 73-percent accuracy. "The gap between human and computational performance is not so big, not as big certainly as it is in other computer vision problems," Hays said.
The program isn't ready to rule Pictionary just yet, mainly because of its limited 250-category vocabulary. But expanding it to include more categories is a possibility, Hays says. One way to do that might be to turn the program into a game and collect the data that players input. The team has already made a free iPhone/iPad app that could be gamified.
"The game could ask you to sketch something and if another person is able to successfully recognize it, then we can say that must have been a decent enough sketch," he said. "You could collect all sorts of training data that way."
And that kind of crowdsourced data has been key to the project so far.
"It was the data gathering that had been holding this back, not the digital representation or the machine learning; those have been around for a decade," Hays said. "There's just no way to learn to recognize say, sketches of lions, based on just a clever algorithm. The algorithm really needs to see close to 100 instances of how people draw lions, and then it becomes possible to tell lions from potted plants."
Ultimately a program like this one could end up being much more than just fun and games. It could be used to develop better sketch-based interface and search applications. Despite the ubiquity of touch screens, sketch-based search still isn't widely used, but that's probably because it simply hasn't worked very well, Hays says.
A better sketch-based interface might improve computer accessibility. "Directly searching for some visual shape is probably easier in some domains," Hays said. "It avoids all language issues; that's certainly one thing."

Facebook’s Got a Reputation Problem: Harris Poll
Nearly 850 million people use Facebook each month and roughly 480 million people use it every day. With a user rate like that and an upcoming $75 to $100 billion initial public offering, one might think Facebook is not only a highly visible company, but also one of Corporate America's most reputable.
But that's not really the case, according to the findings discovered by Harris Interactive. The company recently conducted its 13th annual Reputation Quotient Study, which measures companies' reputation with consumers.
In performing the survey, Harris first asked 17,000 people to chose the companies that are most visible to them on a daily basis. The respondents were then asked to rate the top 60 most visible companies on wide rage of attributes, including emotional appeal, products and services, social responsibility, vision and leadership, workplace environment and financial performance.
Apple bumped Google for the number one spot as the most reputable company in America, followed by Coca-Cola, Amazon.com and Kraft Foods. (See: Apple Ranks #1 With Consumers as J&J Tumbles in Harris Poll: Big Banks Come in Last)
But Facebook did not even make its way onto the most visible list of companies for consumers to rank, which is surprising for a company that has a shocking number of users and plans to go public. So how can this be? Well, it turns out that the public fails to recognize the social networking website as an actual corporation. Most people see Facebook rather as a tool, service or a channel for communication, says Robert Fronk, executive vice president for Harris Interactive.
While Facebook did not make the list this year, unlike last year, Harris still rated the company on its reputation. Facebook received a reputation rating bordering between fair and good, falling short of very good and excellent. The company's reputation waned in 2012 because 25% of the general public holds a negative perception of the company on a wide-rage of issues, including trust and respect. Those feelings are in line with the countless privacy concerns facing the company.
In terms of Facebook's shortcomings, here's what the study found:
People do not trust Facebook to do the right thing if faced with a problem.
People do not believe Facebook maintains high ethical standards.
People do not believe Facebook is sincere in its communications.
People do not believe Facebook is transparent in its communications.
Why does reputation matter anyway?
"One of the reasons companies want to build reputation is so that they can over time build equity so that when a crisis comes along, when they need to influence a particular stakeholder they have build up some of that equity," says Fronk. "And right now Facebook has an equity gap."
As mentioned, Facebook is set to go public in the coming months. But it turns out that only 7% of the general public would purchase shares in the company. Seventeen percent said they definitely would not. And 0% of the general public would recommend the stock to someone else.
"When you are going to be a public corporation there is a burden on you, there is an expectation for you to communicate a little bit more," says Fronk. "What the public is looking for are companies who communicate sincerely, with a certain amount of transparency and honesty and on those measures right now Facebook also has a serious gap."
Tell us what you think! Do you think Facebook has a good reputation? Would you buy stock in the company?
Who's Watching You On Facebook?
There can't be many Internet users who haven't heard of Facebook – the social network site, brainchild of U.S. college student Mark Zuckerberg. But worryingly, it's not just our friends who are keeping up with what we're doing online. Debt collectors, potential employers and even lawyers could be finding out much more than you'd want them to. Here we examine the worrying trends on the social network site and consider how you can take steps to avoid being spied on.
Debt Collector Watch
It seems that debt collectors have caught on to how difficult it is to hide on Facebook. According to MSN Money, debt collectors are infiltrating social network pages, contacting you, your friends and family through the site to force you to pay what you owe.
One debt collection agent, Michelle Dunn, confirms that this is a strategy used by debt collection agencies today. "If you look like a really good-looking girl, a lot of people would accept a friendship even if they don't really know the person," she explains. Luckily the The Fair Debt Collection Practices Act, designed to protect consumers against abusive practices by the debt collection industry, does offer you some protection in this area. Although it is not forbidden for collectors to post on your Facebook wall or ask your contacts of your whereabouts, they cannot post about your debt, because that is a serious breach of privacy. Nevertheless, it should be common practice not to accept friend requests from people you don't know, and of course, if you do owe money, in order to avoid being found and potentially harassed on Facebook, you should answer mail or calls or from collection agencies in the first instance. Ignoring the problem will not make it go away.
Job hunting
When you're applying for a new job, polishing up your resume may not be enough anymore. Rather, you should check what information is out there about you on the web. Facebook profiles are routinely being checked by your future employers. According to a survey carried out by Careerbuilder in 2009, 45% of employers check your social media presence when hiring, and some 35% of employers reported that they have found content on social networking sites that meant they did not hire the candidate. As social media has only grown over the past few years, we can only imagine that this figure would be much higher today.
More than half of the employers questioned said that provocative photos were the biggest factor contributing to a decision not to hire a potential employee, while 44% of employers pinpointed references to drinking and drug use as no-go areas. While this might seem obvious, you can never know what a company might deem "provocative." It seems wise to keep all content absolutely clean, otherwise who knows what job prospects you are thwarting.
Passwords Please
In an even more worrying development in Maryland, a man has recently been asked to hand his Facebook login details over to his employee. He was outraged and made a complaint to the American Civil Liberties Union. As a result the updated policy at the Maryland Department of Corrections states that job candidates won't be asked to share their login or password information, but job applicants will be asked to log into Facebook "voluntarily" as an interviewer looks over their shoulders.
Legal Snooping
Beware what you post on the web, because, as a Staten Island woman recently discovered, the legal profession is snooping too. Dorothy McGurk claimed that she couldn't work, rarely left home and didn't socialize because of injuries from a 1996 car accident. The dancer, on disability, had been seeking lifetime alimony of $850 a month from her husband due to this accident. Unfortunately, Facebook revealed that all was not as it seemed, and showed that she was in fact working as a belly dancer. When the Facebook evidence came to light as evidence in court, the alimony was lost.
The Bottom Line
Unfortunately, many of us fail to realize that content we post on the Internet is really out there in the public domain. If you do want to continue using Facebook, what can you do to protect yourself from unwanted prying eyes? Be sure you've checked those privacy settings. It is sensible to keep any personal content away from the public eye. Also, be careful what you are making available to your networks. It might seem safe enough to let people who graduated from the same college as you view your profile, but this will include several thousand – if not tens of thousands of – people who you have never met nor know, and who may have ulterior motives when checking out your profile. Keep it clean and professional. Ask yourself: would you want your future employer to read this? If the answer is no, don't post it. There's really nowhere to hide on the world wide web.

Dreamliner jet “draws” Boeing logo across North America
A Boeing 787 jet took corporate loyalty to new heights when it "drew" the letters "787" followed by the company's logo across several thousand miles of North American skies. The etching of the letters and logo, while not visible from the ground, can be seen in the flight path plans.
In the above image, you can see the 787 Dreamliner's flight path, which was first reported by Gizmodo. The flight path was meticulously designed and coordinated with airports across the country in or to avoid violating restricted airspace.
"This wasn't a joy ride," wrote Boeing's vice president of marketing Randy Tinseth on the company's blog. "It was an 18 hour Maximum ETOPS (Extended Operations) Duration flight test for a 787-8 with GE engines. Our team coordinated with the many air traffic control centers, choosing the routing to avoid restricted airspace. In the end, the flight covered over 9,000 nautical miles." The path stretched between Iowa and Washington State.
Boeing conducted another sky drawing back in August, reports Wired, when the 747-8 Freighter outlined a "747" over several states. The BBC reported on the Dreamliner's maiden commercial voyage last October, traveling from Tokyo to Hong Kong.
It's an exciting time for air travel enthusiasts. Billionaire developer Paul Allen recently unveiled designs for his company's Stratosphere plane, which is designed to take passengers on commercial voyages above Earth's orbit.
Rewriting The Rules of High Speed Travel
Rewriting The Rules of High Speed Travel
Rewriting The Rules of High Speed Travel, International travel via high-speed tubes, Someday people could zip from New York to Beijing in just two hours, one group believes. Let's say it's the fourth of July, and the Clintons have invited you to their house in Westchester, New York to shoot off some fireworks and have a barbeque. From Grand Central station in New York City, it would take you an hour to get there by train. Well, imagine being able to travel to London in less time to meet the Queen for tea at Buckingham palace.
A licensing organization called ET3 believes that day isn't far off. They hold a patent to Evacuated Tube Technology or ETT and say that with their tubes, you will eventually be able to get you from New York to Beijing in 2 hours and from New York to London in less than an hour.
Their six person capsules would travel on frictionless magnetic levitation tracks, through air-less vacuum tubes reaching a maximum speed of 4,000 miles per hour. At that speed you could spend the day comparing noodles in China to Pasta in Italy and back to New York in time for cheesecake, all in the same day.
Now before you start making dinner reservations in Tuscany and sending out an RSVP to the Royal Family, this technology is still a concept and it's not clear when it will be operational. The first prototype is being built by researchers at Southwest Jiaotong University in China, who licensed ET3's technology and have worked with the founder of the company to build it.
If you're interested in getting involved, it's an open source technology and you can buy a lifetime license for a hundred dollars allowing you to propose and bid on related construction of the rails.
Homes for the price of a car
A house for the price of an SUV? That’s plausible, given the dip in housing. But a home for the price of a Ford Fiesta?
1620 W 2nd N, Wichita, KS
For sale: $54,900
Whoa. Now there’s a value-bending proposition.
While most people don’t think of real estate in prices relative to that of a car, there are houses in some parts of the United States that are for sale with listing prices just like what you’d see at an auto dealership.
And we’re not talking about a house priced at the median home value of $150,000, which is akin to the sticker price of an Aston Martin. The homes featured below compare more favorably to standard highway fare: Nissans, Hondas, Fords, etc.
Some of these properties are distressed sales — either foreclosed or in the midst of a short sale — and some need a little renovation, but that’s still a pretty impressive given that they’re all comparable to the price of a new car.

Fold-up car of the future unveiled for Europe
A tiny revolutionary fold-up car designed in Spain's Basque country as the answer to urban stress and pollution was unveiled Tuesday before hitting European cities in 2013.
The "Hiriko," the Basque word for "urban," is an electric two-seater with no doors whose motor is located in the wheels and which folds up like a child's collapsible buggy, or stroller, for easy parking.
Dreamt up by Boston's MIT-Media lab, the concept was developed by a consortium of seven small Basque firms under the name Hiriko Driving Mobility, with a prototype unveiled by European Commission president Jose Manuel Barroso.
Demonstrating for journalists, Barroso clambered in through the fold-up front windscreen of the 1.5-metre-long car.
"European ideas usually are developed in the United States. This time an American idea is being made in Europe," consortium spokesman Gorka Espiau told AFP.
Its makers are in talks with a number of European cities to assemble the tiny cars that can run 120 kilometers (75 miles) without a recharge and whose speed is electronically set to respect city limits.
They envision it as a city-owned vehicle, up for hire like the fleets of bicycles available in many European cities, or put up for sale privately at around 12,500 euros.
Several cities have shows interest, including Berlin, Barcelona, San Francisco and Hong Kong. Talks are under way with Paris, London, Boston, Dubai and Brussels.
The vehicle's four wheels turn at right angles to facilitate sideways parking in tight spaces.
The backers describe the "Hiriko" project as a "European social innovation initiative offering a systematic solution to major societal challenges: urban transportation, pollution and job creation."
Steve Jobs brought back to life as an Android fan in Taiwanese ad
Taiwan's Action Pad uses Steve Jobs look-alike to drum up support, but has it backfired?
In the months following long-time Apple CEO Steve Jobs's untimely death, we've seen him resurrected in many forms. He's already been brought back in plastic and bronze, but we never thought we'd see him reborn as an Android supporter. Leave it to a Taiwanese tablet maker to dream up such a thing, and recreate an iconic Apple keynote presentation in the process.
The makers of the Taiwanese Action Pad tablet went to great lengths to honor (or mock?) the world-famous Apple co-founder by dressing a Taiwanese lookalike in Jobs's popular black turtleneck and Levi's blue jeans. For good measure, the Jobs-alike is even equipped with a heavenly halo and angel wings.
The fake CEO trots about a stage that looks very much like the ones Apple uses for its major product announcements, but it's not an iPad in his hands — it's the overseas knockoff. The ad boasts that the Action Pad is "the new generation of the pad," and shows off various app icons ranging from an RSS reader to the recognizable Android mascot.
In a move that you'd never see the real Steve Jobs make, the angelic speaker touts the benefits of the Android 2.3 operating system that comes standard on the Action Pad, and even goes so far as to say "Thank God I can finally play another pad."
While it might seem less than tasteful, the ad doesn't actually use Jobs's name or any copyrighted material that could land the Action Pad's manufacturers in legal trouble. However, that hasn't stopped many commenters from lambasting the parody on video hosting sites where it appears. Even diehard Android fans are coming out against the clip, calling it "very disturbing," and "extremely disrespectful."
The tablet itself is nothing particularly special: It appears to be wifi-only with no 3G or 4G mobile connection options, and its Android 2.3 operating system is somewhat outdated as nearly all new Android slates come with a much newer version. Whether the off-color commercial will help the Action Pad gain traction remains to be seen, but with many calling for a boycott of the company as a whole, it might prove more of a curse

Porsche-designed condo lifts owners and cars to high-rise homes
Sean Gallup/Getty Images
The big problem for builders of luxury homes in the cities where wealthy people choose to live is the sheer lack of space, especially for parking a small fleet of vehicles. Which is why one Miami Beach condo developer plans to build a new skyscraper with a robotic parking deck built in.
The $560-million Porsche Design Tower project as described by the Miami Herald will allow owners to ride their vehicles into a robotic elevator system that drops them and their vehicles at their doorstep. The condos were designed by Porsche Design Group, a spinoff of the German automaker that lends its style to everything from office complexes to cellphones. (Developer Gil Dezer also has Porsche body panels mounted on his walls.)
The condo will have 132 units over 57 stories, with larger units sporting up to four parking spaces per unit. Porsche didn't have to go far for inspiration, as the tower is similar in design to Volkswagen’s Autostadt in Wolfsberg, Germany, shown above, a 20-story robotic parking garage that VW uses to deliver cars to new buyers. Really, it's the only way to valet.
25 "Worst Passwords" of 2011 Revealed
If you see your password below, STOP!
Do not finish reading this post and immediately go change your password -- before you forget. You will probably make changes in several places since passwords tend to be reused for multiple accounts.
Here are two lists, the first compiled by SplashData:
1. password
2. 123456
3.12345678
4. qwerty
5. abc123
6. monkey
7. 1234567

Last year, Imperva looked at 32 million passwords stolen from RockYou, a hacked website, and released its own Top 10 "worst" list:
1. 123456
2. 12345
3. 123456789
4. Password
5. iloveyou
6. princess
7. rockyou
8. 1234567
9. 12345678
10. abc123
If you've gotten this far and don't see any of your passwords, that's good news. But, note that complex passwords combining letters and numbers, such as passw0rd (with the "o" replaced by a zero) are starting to get onto the 2011 list. abc123 is a mixed password that showed up on both lists.
Last year, Imperva provided a list of password best practices, created by NASA to help its users protect their rocket science, they include:
It should contain at least eight characters
It should contain a mix of four different types of characters - upper case letters, lower case letters, numbers, and special characters such as !@#$%^&*,;" If there is only one letter or special character, it should not be either the first or last character in the password.
It should not be a name, a slang word, or any word in the dictionary. It should not include any part of your name or your e-mail address.
Following that advice, of course, means you'll create a password that will be impossible, unless you try a trick credited to security guru Bruce Schneir: Turn a sentence into a password.
For example, "Now I lay me down to sleep" might become nilmDOWN2s, a 10-character password that won't be found in any dictionary.
Can't remember that password? Schneir says it's OK to write it down and put it in your wallet, or better yet keep a hint in your wallet. Just don't also include a list of the sites and services that password works with. Try to use a different password on every service, but if you can't do that, at least develop a set of passwords that you use at different sites.
Someday, we will use authentication schemes, perhaps biometrics, that don't require so much jumping through hoops to protect our data. But, in the meantime, passwords are all most of us have, so they ought to be strong enough to do the job.
